    Innovation for contamination control and worker protection improvement

    Sources: Bertin Instruments, France


    Equipped with an aging fleet of contamination control instruments, EDF wanted to replace its old monitors with new equipment, more efficient and enabling an easier control, while being compatible with the majority of probes available on the market.

    In order to meet this demand, the group called upon Bertin’s expertise to develop a new comprehensive and innovative contamination control system, in compliance with the ALARA approach, applicable in the nuclear industry.


    Alpha and beta radiation having a limited path in the air (see Fig.1), contamination control must be carried out closest to the surface to be analyzed. Positioning the detector correctly in order to carry out the control efficiently is crucial.

    One of the major innovations of the SaphyRAD E is the integration of distance sensors in the probes, coupled with visual and audible status alarms, to answer this problem. These sensors make it possible to ensure the operator that the measurement is made correctly, at the right distance, and under the best possible conditions.


    With its new innovative and ergonomic features, the SaphyRAD E facilitates and optimizes contamination control at zone & site exits, in order to reduce the doses received by workers.
